GAS OR HYDROCABBON-VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 446,016, dated February10, 1891.

Application filed October 23, 1890. Serial No. 869,041. (No model.)

To aZZ 1071/0111] it may concern:

Be it knownthat I, GEORGE Ronnnrs, a subject of the Queen of GreatBritain, residing at the city of Montreal, in the District of Montrealand Province of Quebec, Canada, have invented new and usefulImprovements in Gas or Hydrocarbon-Vapor Burners; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

This invention has reference to the construction of a burnerwhich may beused for heating orlighting purposes, or both, in which gas, gasoline,or hydrocarbon vapor may be used to generate the desired heat or light.When used as a heater, it may be placed inside a stove fire-grate,furnace, or under a stand, and although the invention may be made insingle form yet I prefer to make it. of a number of folds or sections,so that by the use of"a greater or less number of sections the heat andlight may be regulated to a greater extent than can be accomplished bythe adjustment of the ordinary stop-cocks by which the flow of gas, &c.,to the whole burner is controlled; and the object of my invention is toprovide a more convenient form of gasheater for general use, and toconstruct the invention so thatit will be very light, port able, andsuitable to be connected with any gas pipe orburner in the apartment ofahouse by means of a flexible hose, and may also, if desired, be appliedto stationary stoves, (be. I attain these objects by the burnerillustrated in the accompanying drawings, in which similar letters ofreference indicate like parts. i

Figure 1 is a plan of the burner. Fig. 2 is a part side elevation andpart section. The section of the parts that are shown in section istaken at line 0;, Fig. 1, while the pipeo and cap 13 are shown inelevation. Fig. 3 is a half end elevation and half transverse section ofthe burner, the sectional part being taken at line 00, Fig. 1. Fig. i isa plan of the under side of the extremity of the branch pipe g, showingthe opening t. Fig. 5 is a section of the end of the branch pipe q,sleeve to, and pipe 1), taken on line m Fig. 2.

a is a rectangular casing carried on supports 1) at any desired height.This is adapted to support within it a horizontal perforated diaphragm.c.

As shown, the invention is of duplicate form, the space between theperforated diaphragm 0 being divided into two parts by a diaphragm cl,extending the entire length of the casing a, and from the bottom 6 up tothe under side of the diaphragm c. If desired, however, the width of thecasing may be increased, and it may be divided into a greater number ofparts, thus enabling the burner to be made in a corresponding number offolds or sections.

In the bottom a of the casing a openings 6 are formed to each of thesections 6 for the air to pass up through, and, as shown, a damper e isprovided to each, so that the openings for the passage of air may beadjusted in size or altogether closed.

f is a casing fitted to the top of the casing a, resting by its edgesupon the edges of the diaphragm c. This is provided with a longitudinaldiaphragm g, dividing itinto sections h, agreeing with the sections i ofthe casing a. Each section has an arched top 7o, having an opening Z.The edges of the arched top are bent under and formdownwardly-projecting ridges m. These are provided with perforations iton both sides of the openings Z. Each section h has a gas-pipe o,passing longitudinally through it in the position shown.

17 are caps closing one end of the pipes, while the other ends areconnected with a branch pipe q.

r are perforations which serve as ordinary burner-jets. These and theperforations a may, if desired, be made in the form of elongatedopenings or slits.

s are stop-cocks, one for each pipe 0.

In. the main part of the branch pipe g, on its under side, an opening 25is formed, as shown, this orifice being similar to that of a commonwhistle. Over this said part of the pipe 1 is closely fitted a sleeveto, having a corresponding opening to the opening t.

In the end of the pipe q is screwed anipple v, having an orifice a, theparts being so arranged that the orifice a will come nearly flush withthe opening 2%, as will be seen by comparing Fig. l with Fig. 5. Thenipple is made integral with a pipe I), which may be connected in anydesired manner with any ordinary gas-pipe in the room in which theburner is to be used. The burner thus constructed may be situated withinthe fire-place of any stove, cooking-stove, furnace,fire-place, or openwork, or inclosed casin g c, which may be provided with mica or otherlights to allow the light emitted from the burner to radiate within theapartmentin which the burner is situated.

In operating the said burner when made of a number ofsections greaterthan one, any desired number of sections may be put in operation at thesame time by opening the corresponding stop-cocks s and lighting the gasor vapor escaping from the perforations 0'. Such of the sections as arelighted will have the dampers 6 opened to allow a current of air to passup through them. This current of airis by the diaphragm c distributed orprevented from rising locally from the openings 6, being thereby made torise equally throughout the whole area of the sections 7L, in doingwhich a portion of it is caught by the ridges m and caused to form jetsof air by passing through the perforations 'n to act on both sides ofthe flame from the perforations r of the pipe 0. Should any of thesections h not be put into operation, the dampers e of those sectionswill be closed to prevent a current of cold air passing up, and have adetrimental effect by intermingling with the heat produced by thesections in operation.

3y the openingtan amount of air is admit ted to intermingle with thegas, &C., escaping from the nipple 'v. This opening may be regulated insize, and consequently the amount of air admitted through it, byadjusting the position of the sleeve it upon the main portion of thebranch pipe q.

What I claim is as follows:

1. The combination, in a burner for gas, gasoline, or hydrocarbon vapor,of the casing a, having damper or dampers c and openings 6, section orsections 2, perforated diaphragm c, with a casing f, havingcorresponding sec-- tions h, each provided with a pipe 0, havingperforations r, and each provided with openings Z, downward-extendingridges an, having perforations n, the whole constructed and arrangedsubstantially as shown and described.

2. The combination, in a burner for gas, gasoline, or hydrocarbon vapor,of the casing a, having damper or dampers e and openings 6', section orsections 2 perforated diaphragm c, with a casing f, having correspondingsections h, each provided with a pipe 0, having perforations r, and eachprovided with opening Z, downward-extending ridges m, havingperforations n, with a branch pipe q, having adjustable opening 25 forthe admission of air, the whole constructed and arranged to operatesubstantially as shown and described, for the purposes set forth.
